Large number of Serbian M1899 and M1910 Mauser rifles were captured by the Austro-Hungarian forces in Serbia in 1914-15.
Captured rifles were issued to 2nd line units in unaltered condition, with captured 7x57mm Mauser ammunition. The rifles were designated '7mm M.14'.
Oberndorf made M1899 rifles carry a cyrillic side rail legend: 'ORUZHNA FABRIKA MAUZERAD OBERNDORF'. Original rifles had a straight stock, no pistol grip.

The Model 99/07 rifle is nearly identical to the M1899. A Model 99/08 was also manufactured, which was apparently identical to the M99/07, except for the
Model designation. Austro-Hungary did not differentiate between the captured M1899 and M99/07 and M99/08 rifles.
Steyr made M1899/07 rifles carry a cyrillic side rail legend: 'AUSTRIJSKA ORUZHNA FABRIKA STAJER'.

A few Serbian Mauser Model 1908 carbines were captured along with the rifles. Austro-Hungary did not differentiate with a unique designation between the
captured M1899 and M99/07 rifles and th M1908 carbine.
The M1908 carbines were made by Steyr and carry a cyrillic side rail legend: 'AUSTRIJSKA ORUZHNA FABRIKA STAJER'. The carbine's action is the similar to
the Chilean M1895. The M1908 has a turn-down bolt, a Steyr-style pistol grip, stocked to the muzzle, no bayonet lug.
